vdimm setting

I can't seem to find a setting for the vdimm voltage......maybe my bios/motherboard doesn't have one, what should i do?

thanks

mobo- Asus A7V 266

I don't think your mobo's bios has a vdimm option. I know the A7V333 doesn't but has jumpers on the mobo to adjust the VDIMM.
Your mobo might have it too. Examine your mobo real closely and you might fnd some jumpers for it.
